COUPLING DEVICE...

SPECIFICATION forming part of Letters Patent No. 788,692, dated May 2, 1905. Application filed July 15, 1904. Serial No. 216,647.

To all whom it may concern:

Be it known that I, HENRY AMMANN, aciti- Zen of the United States, residing at Mayfield, in the county of Sumner and State of Kansas, have invented certain new and useful Improvements in Coupling Devices; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a coupling device that will be automatic in its action and applicable to all purposes where a coupler of the character hereinafter described. may be found useful, especially on a traction-engine to couple the separator thereto, thereby securing a perfect action of the coupler in releasing the load when on the move or pulling with ease and coupling when in any position.

The invention consists in a coupling device constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a perspective View of the coupling device; Fig. 2, a sectional elevation through the coupling-head, showing the operating parts in elevation previous to coupling; Fig. 3, a similar view showing the operating parts in the position they will assume when the coupling-link is coupled to the coupling-head; Fig. 4, a sectional view taken on line 4 4 of Fig. 3; Fig. 5, a detailed perspective view of the pivotal end of the coupling-lever.

1n the accompanying drawings, A represents the coupling-head, and B the couplinglink, adapted to engage therewith, said head and link being of any preferred form and construction found best adapted to the purpose.

The coupling-head A is formed with a recess or chamber a and at its front a bifurcation b to receive the end of the coupling-link B, as shown in Figs. 3 and 4 of the drawings, which link is illustrated as in an engaged position with the coupling-head. Within the recesses or chamber a of the coupling-head A and between the walls thereof are the operating parts of the coupling device and consists, in part, of

the locking-lever C, suitably pivoted to the walls of the coupling-head, as indicated at c, which lever is spring-actuated through the medium of the spring D. This spring is suitably connected to the front end of the coupling-head, and its free end bears against a flange (Z on the pivoted end of the locking-lever and lies between said flange and a stop 0.

The locking-lever C is provided with a bearing-finger f and a stop 5 which may be of any preferred construction, and pivoted at it to the walls of the coupling-head is a draftjaw E, and to the draft-jaw is pivoted a tripdog F, at the front end thereof. The lockinglever O is further provided with a shoulder f,

(seen clearly in Fig. 5,) adapted to engage the square portion 6 on the inner upper end of the draft-jaw E to hold the locking-lever C in the position in which it is seen in Fig. 2.

To the draftjaw E is pivoted a trip-lever Gr, one end thereof, as indicated at t', engaging a notch fin the trip-dog F and the opposite end of the trip-lever having a curve, as shown at it, so that the end of the lever will be brought into position so that the stop 9 on the locking-lever G will come in contact therewith when the operating parts of the coupling-head are in position to lock the couplinglink B of the d raw-bar H in engagement with the coupling-head, as'shown in Fig. 3 of the drawings.

The front ends of the draft-jaw E and the trip-dog F have camfaces Zm, respectively, i

so that the coupling-link B can ride over the same and automatically couple itself to the coupling-head when the operating parts thereof are in a released position, and when the link strikes the cam-faces the operating parts will assume the position indicated in Fig. 2 of the drawings, and when the link of the draw-bar strikes the trip-arm n of the draftjaw E the operating parts of the couplinghead will automatically assume a locking position to securely hold the coupling-link thereto, as shown in Fig. 3 of the drawings.

The trip-dog F is considered of material im portance and essential for coupling when the draft-jaw E is closed-as, for instance, should the draft-jaw be closed the trip-dog would always keep it ready and in position for coupling, the trip-lever G keeping the trip-dog always in a coupling position and ready to couple.

The lock-lever C is perfect in its action, and the general construction of the coupling device enables a perfect action of the parts and will release its load much easier and surer than the coupling devices of ordinary construction and will couple at any position, the device being simple in construction and the cost of manufacture materially reduced, thereby providing a coupling device possessing many advantages, as Well as being strong and durable.

It is evident that many changes and modifications may be resorted to without in any manner departing from the essential features of the invention, and such changes as would come within ordinary mechanical judgment may be made in the several details of construction without affecting the successful operating of the coupler.

Having now fully described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

A coupling device comprising a suitable coupling-head, a spring-actuated locking-lever pivoted to said head and having a bearing-finger and a stop, a pivoted draft-jaw having a trip-arm, a notched trip-dog pivoted to the draft-jaw, and a trip-lever pivoted to the draft-jaw and adapted to engage the trip-dog and having a curved end to engagethe stop of the locking-lever, substantially as and for the purpose set forth.

In testimonywhereofl afiix my signature in presence of two witnesses.

HENRY AMMANN.
